Embodiment 1

[0033] Such as figure 1 As shown, this embodiment provides an industrial Internet of Things system for marine engineering equipment, including:

[0034] Infrastructure layer: The infrastructure layer includes a certificate management unit, a digital signature unit, a consensus mechanism unit, and a smart contract unit; using a blockchain architecture, the infrastructure layer is used to store secondary identification data and record information for secondary identification data operations. The blockchain adopts the form of alliance chain, encrypts the user identity and identification data of marine engineering equipment based on the elliptic curve encryption algorithm, and uses the practical Byzantine fault tolerance mechanism to conduct transaction authentication on the secondary identification data of marine engineering equipment.

[0035] Middleware layer: The middleware layer includes a distributed identity authentication unit, an active identification service unit, and a ...

Embodiment 2

[0039] Such as figure 2 As shown, this embodiment provides a method for storing marine identification data based on the above-mentioned industrial Internet of Things system oriented to marine equipment, including the following steps:

[0040] (1) Obtain the secondary identification data of offshore equipment uploaded through the smart terminal in the offshore equipment supply chain;

[0041] (2) Submit the request for uploading the secondary identification data of the offshore equipment through the blockchain node of the offshore equipment;

[0042] (3) Invoke the smart contract deployed in the infrastructure layer according to the chain request, and submit the chain request to the middleware layer;

[0043] (4) Obtain the country's top node configuration information by calling the secondary node configuration routing information;

[0044] (5) Conduct transaction authentication (endorsement, sorting, verification) on the secondary identification data and configuration infor...

Embodiment 3

[0050] Such as Figure 4 As shown, this embodiment provides a marine engineering identification data query method based on the above-mentioned industrial Internet of Things system oriented to marine engineering equipment, including the following steps:

[0051] (1) Obtain the identity of the user who requests the second-level identification data query of the offshore engineering equipment for identity verification;

[0052](2) Invoke the smart contract deployed at the infrastructure layer according to the secondary identification data query request command issued by the user who passed the identity verification;

[0053] (3) According to the invoked smart contract, send a query request for secondary identification data of marine engineering equipment to the middleware layer, configure the routing information through the secondary node, and call the top node of the country to obtain the index information;

[0054] (4) Query on the blockchain of the infrastructure layer accordi...

Abstract

The invention discloses an industrial Internet of Things system and a maritime work identification data storage and query method, and the method comprises that an infrastructure layer employs a block chain architecture and is used for storing maritime work equipment secondary identification data and recording information of secondary identification data operation; a middleware layer is used for realizing data exchange between a national top-level node and a maritime work equipment industry second-level node by acquiring calculation and storage resources provided by the infrastructure layer; a platform layer is used for building a secondary node function system, and the secondary node function system is upwards butted with a national top-level node and downwards butted with an enterprise node, a mechanism node and a recursive node in the maritime work equipment industry; an application layer is connected with the middleware layer, verifies an identifier query instruction of a user and displays a secondary identifier data traceability result. According to the invention, storage and query of the secondary identification data can be realized, data interaction operation among different identities is realized, and the invention has the advantages of safety and reliability based on the block chain.

Description

technical field [0001] The invention relates to an industrial internet of things system and a marine engineering identification data storage and query method, belonging to the technical field of industrial internet. Background technique [0002] The offshore engineering equipment supply chain involves cross-domain and cross-regional users, the user information is complex and the item identification data is not uniform, which makes it difficult to analyze the secondary identification data of the offshore engineering equipment; the users of the offshore engineering equipment supply chain are distributed on different information platforms, making cross- Platform data sharing and exchange are difficult to achieve; under the background of big data, the amount of identification data information is huge, and the value mining and safety management of secondary identification data of marine engineering equipment are challenged. The second-level node identification is the unique ident...
